Ungahlola kanjani i-cap radiator

Ungahlola kanjani i-cap radiator? Lo mbuzo ubuzwa abashayeli ngezikhathi ezahlukene zonyaka. Phela, ukusebenza kwekepisi ye-radiator kunikeza ingcindezi eyengeziwe ohlelweni lokupholisa injini yangaphakathi, okwenza kube nokwenzeka ukuthi injini yomlilo yangaphakathi isebenze ngokujwayelekile futhi isitofu sangaphakathi sisebenze ngenkathi ebandayo. Ngakho-ke, isimo saso kufanele siqashwe njalo, futhi uma kudingekile ukushintsha i-valve, indandatho yokuvala uphawu, noma isembozo sonke, ngoba ngokuvamile kuyisakhiwo esingenakuhlukaniswa. Ngakho-ke, ukuze uhlole ukuthi ikhava isebenza kanjani, ukuhlola okukodwa okubonakalayo akwanele, ukuhlolwa kokucindezela kuyadingeka.

Isebenza kanjani ikepisi lerediyetha

Ukuze uqonde kangcono ingqikithi yokuhlola i-cap ye-radiator, okokuqala udinga ukuxoxa ngesakhiwo sayo kanye nesifunda. Okokuqala, kufanele kuqashelwe ukuthi i-antifreeze ohlelweni lokupholisa ingaphansi kwengcindezi ephezulu. Lesi simo senziwa ngokukhethekile ukuze kwandiswe indawo yokubilisa yesipholile, njengoba izinga lokushisa elisebenzayo lenjini evuthayo yangaphakathi lidlula kancane i-+100 degrees Celsius. Imvamisa, indawo yokubilisa ye-antifreeze izungeze + 120 ° C. Kodwa-ke, kuncike, okokuqala, ekucindezelweni ngaphakathi kwesistimu, futhi okwesibili, esimweni sokupholisa (njengoba iminyaka ye-antifreeze, iphuzu layo lokubilisa liyancipha).

Ngesivalo serediyetha, akukhona nje ukuthi i-antifreeze ithululelwa endlini ye-radiator (nakuba i-antifreeze ivamise ukungezwa ethangini lokunweba lesistimu ehambisanayo), kodwa isipholile esiguqulelwe ku-steam siphinde singene ethangini lokunweba ngalo. Idivayisi yekepisi yerediyetha yemoto ilula kakhulu. Ukwakhiwa kwayo kuhilela ukusetshenziswa kwama-gaskets amabili nama-valve amabili - i-bypass (elinye igama umusi) kanye nomkhathi (elinye igama i-inlet).

I-valve ye-bypass iphinde ifakwe ku-plunger elayishwe entwasahlobo. Umsebenzi wawo ukulawula kahle ukucindezela ngaphakathi kwesistimu yokupholisa. Ngokuvamile imayelana 88 kPa (ihlukile izimoto ezahlukene, futhi kuncike nezimo zokusebenza injini omlilo yangaphakathi injini ethile yangaphakathi omlilo). Umsebenzi we-valve yasemkhathini uphambene. Ngakho-ke, yakhelwe ukuqinisekisa ukulingana kancane kancane komfutho womoya kanye nokucindezela okwenyukayo ngaphakathi kwesistimu yokupholisa esimweni lapho injini evuthayo yangaphakathi icishiwe futhi iphole. Ukusetshenziswa kwe-valve yasemkhathini kunikeza izici ezimbili:

• Ukweqa okubukhali kwezinga lokushisa kwesipholile ngesikhathi lapho ima khona iphampu akufakiwe. Okusho ukuthi, ukushisa kokushisa akufakiwe.
• Ukwehla kwengcindezi ohlelweni kususwa ngesikhathi lapho izinga lokushisa lesipholisa liyancipha kancane kancane.

ngakho-ke, izizathu ezibalwe ziyimpendulo yombuzo, yini ethinta i-cap ye-radiator. Eqinisweni, ukwehluleka kwayo okuyingxenye ngokuvamile kuholela eqinisweni lokuthi indawo yokubilisa ye-antifreeze iyancipha, futhi lokhu kungaholela ekubiliseni kwayo ngesikhathi sokusebenza kwenjini, okungukuthi, ukushisa ngokweqile kwenjini yomlilo yangaphakathi, yona ngokwayo eyingozi kakhulu!

Izimpawu zekepisi yerediyetha ephukile

Umnikazi wemoto welulekwa ukuthi ngezikhathi ezithile ahlole isimo se-radiator cap, ikakhulukazi uma imoto ingeyona entsha, isimo sesistimu yokupholisa siphakathi noma ngaphansi kwalokhu, futhi / noma uma amanzi noma i-antifreeze ehlanjululwe ngayo yayisetshenziswa njengesipholisa. . futhi, isimo sekhava kufanele sihlolwe esimweni lapho i-antifreeze isetshenziswa ohlelweni lokupholisa isikhathi eside ngaphandle kokuyishintsha. Kulokhu, kungase kuqale ukugqwala uphawu lwenjoloba ngaphakathi kwekhava. Isimo esifanayo singavela, isibonelo, lapho amafutha angangena endaweni epholile lapho i-cylinder head gasket ibhobozwa. Lolu ketshezi lwenqubo luyingozi ku-cap seal, futhi luthunaza nokusebenza kwe-antifreeze.

uphawu oluyisisekelo lokuwohloka kuleli cala ukuvuza ngaphansi kwekepisi ye-radiator. Futhi uma kunamandla, isimo sibi nakakhulu, nakuba ngisho nokuvuza okuncane koketshezi, ukuxilongwa okwengeziwe, ukulungiswa noma ukushintshwa kwekhava kufanele kwenziwe.

Kukhona nezimpawu ezimbalwa ezingaqondile zokuthi isivalo serediyetha aliwubambi ukucindezela ohlelweni lokupholisa. Lokhu kubandakanya:

• izinti ze-bypass valve plunger (ezivamise ukusonteka) ngesikhathi sokunyakaza kokubuya ukuze kucindezelwe;
• ukuwohloka komthombo wekhava;
• lapho i-valve yasemkhathini ikhishwa esihlalweni sayo (isihlalo), iyanamathela futhi / noma ayibuyeli kuyo ngokugcwele;
• ububanzi be-valve gasket bukhulu kunobubanzi besihlalo sayo;
• ukuqhekeka (ukuguguleka) kwama-gaskets enjoloba endaweni engaphakathi yesivalo serediyetha.

Ukwephuka okusohlwini kungabangela isivalo serediyetha ukuthi sidedele isibandisi (i-antifreeze noma i-antifreeze). Kukhona futhi izimpawu ezimbalwa ezingaqondile zokwehluleka kwekhava. Kodwa-ke, zingaphinda zibonise okunye, okubi kakhulu, ukuphazamiseka ohlelweni lokupholisa. Yebo, afaka:

• lapho i-valve ye-bypass ibambekile, ipayipi le-radiator elingenhla liyakhukhumala;
• lapho i-valve yasemkhathini ibambekile, ipayipi le-radiator elingenhla liyahlehla.

futhi uma i-valve eyodwa noma enye ingasebenzi kahle, ukuthi izinga lokupholisa ithangi lokunweba lizofana. Ngaphansi kwezimo ezijwayelekile, kufanele ishintshe (yize kancane) kuye ngezinga lokushisa lenjini evuthayo yangaphakathi.

Ungahlola kanjani ukusebenza kwekepisi ye-radiator

Ungahlola impilo ye-cap ye-radiator ngezindlela eziningana. Ukuze wenze lokhu, landela i-algorithm engezansi.

Kuyadingeka ukuhlola i-cap ye-radiator lapho injini yomlilo yangaphakathi ipholile ngokuphelele, njengoba ingxenye izoba nezinga lokushisa eliphezulu lokupholisa. Uma uyithinta lapho kushisa, ungazishisa wena! Ngaphezu kwalokho, i-antifreeze eshisayo isesimweni esingaphansi kwengcindezi. Ngakho-ke, lapho isivalo sivuliwe, singaphuma, esisongela nangokusha okukhulu!

• Ukuhlola okubonakalayo. Okokuqala, udinga ukubheka ngokubukeka isimo sekhava. Okufanelekile, akufanele kube nokulimala komshini, ama-chips, ama-dents, ama-scratches, njalonjalo. Uma lokhu kulimala kwenzeka, khona-ke ngokushesha noma kamuva isikhungo sokugqwala sizovela endaweni yabo, esizokhula njalo. Isembozo esinjalo singahlanzwa futhi sipendwe kabusha, noma sifakwe esisha. Inketho yesibili ingcono.
• Isheke lasentwasahlobo. Idizayini yekepisi yerediyetha ngayinye ihlanganisa isiphethu esisebenza njengengxenye yevalvu yokuphepha. Ukuze uhlole, udinga ukuyikhama ngeminwe yakho. Uma isiminyaniswe kalula, kusho ukuthi ayisebenziseki futhi idinga ukushintshwa (uma kwenzeka isivalo sigoqeka). Kodwa-ke, ngokuvamile izembozo azihlukaniseki, ngakho-ke kufanele zishintshwe ngokuphelele.
• Hlola i-valve ye-atmospheric. Ukuze uyihlole, udinga ukuyidonsa futhi uyivule. bese udedela futhi uhlole ukuze uqiniseke ukuthi ivala ngokuphelele. futhi phakathi nenqubo yokuhlola, kubalulekile ukuhlola isihlalo se-valve ukuthi kukhona ukungcola noma amadiphozithi kuso, okungase kuvele ngesikhathi sokuhwamuka kwe-antifreeze endala. Uma ukungcola noma amadiphozithi atholakala, khona-ke kunezinketho ezimbili. Okokuqala ukuzama ukuhlanza isihlalo sehhashi. Okwesibili ukufaka esikhundleni sekhava entsha. Kodwa-ke, konke kuncike ezingeni lokungcoliswa kwendawo yangaphakathi ye-vacuum valve.
• Hlola ukusebenza kwe-valve. Ukuze wenze lokhu, udinga ukusebenzisa idivayisi ekhethekile. Mayelana naye kancane.

Kukhona indlela ebizwa ngokuthi "yabantu" yokuhlola isimo sekepisi ye-radiator. Kubandakanya iqiniso lokuthi, enjinini evuthayo yangaphakathi (evuliwe) efudumele, yizwa ipayipi le-radiator. Uma kukhona ukucindezela kuwo, khona-ke isembozo sibambe, futhi uma ipayipi ithambile, i-valve kuyo iyavuza.

Nokho, kukhona futhi incazelo yendlela eyodwa "yabantu", empeleni engalungile. Ngakho-ke, kushiwo ukuthi udinga ukucindezela ipayipi elingaphezulu ngesandla sakho, kuyilapho ngesikhathi esifanayo uqaphela ukwanda kwezinga le-liquid ku-tank yokwandisa. Noma, ngokufanayo, ngokudiliza isiphetho sepayipi lokuphuma, bheka ukuthi i-antifreeze izophuma kanjani kulo. Iqiniso liwukuthi ikholomu ye-liquid iphakamisa isihlalo se-valve kuphela esimweni lapho ukucindezela okuvela emandleni okucindezela kuzoba kukhulu kakhulu. Eqinisweni, njengoba ukucindezela kwanda, uketshezi lucindezela kuzo zonke izinkomba, futhi luzophakamisa kuphela i-valve ye-bypass "ngokweqile". Futhi ingcindezi ye-coolant isatshalaliswa kuzo zonke iziteshi, hhayi nje endaweni eyodwa (esihlalweni).

Ukuhlola isivalo ngezindlela ezithuthukisiwe

Ukuhlola ukusebenza kwe-valve ye-bypass kulula kakhulu. Ukuze wenze lokhu, udinga ukunqamula noma iyiphi ipayipi encane yesistimu yokupholisa enjini yangaphakathi yomlilo, isibonelo, ukushisa i-damper noma i-manifold. khona-ke udinga ukusebenzisa i-compressor nge-gauge yokucindezela (ukuze wazi ingcindezi yokuhlinzeka ngokuqondile), udinga ukunikeza umoya ohlelweni. Inani lokucindezela lapho i-valve esebenza khona lizonqunywa kalula ukuhiliza nokubhodla okuvela ezintweni zesistimu yokupholisa. Sicela uqaphele ukuthi ekupheleni kwenqubo, ingcindezi ayikwazi ukukhululwa kungazelelwe. Lokhu kusongela ngokuthi lapho isivalo sivulwa, i-antifreeze ingase iphume ngaphansi kwengcindezi. Ngaphansi kwezimo ezijwayelekile, i-valve yasemkhathini iklanyelwe ukuvimbela lokhu.

Kusukela ku-tank yokwandisa, uketshezi lungena ku-radiator nge-valve yokuhlola. Igcina ukucindezela okuvela ohlangothini lwe-radiator, kodwa ivula ngokuthula uma kukhona i-vacuum ephelele lapho. Ihlolwa ngezigaba ezimbili:

1. Udinga ukuzama ukuphakamisa isiqeshana se-valve ngomunwe wakho. Ngokufanelekile, kufanele ihambe ngomzamo omncane (akukho ukumelana nomshini).
2. Enjinini evuthayo yangaphakathi ebandayo, lapho kungekho ngcindezi eyeqile kurediyetha, udinga ukufaka ipulaki esihlalweni sayo. bese unqamula ishubhu eya ethangini lokunweba lesistimu yokupholisa bese uzama "ukufuthela" irediyetha. I-valve yenzelwe ukucindezela okuphansi, ngakho-ke cishe uzokwazi ukuphefumula inani elincane lomoya owedlulele ku-radiator. Lokhu kungahlolwa ngokukhulula ikepisi yerediyetha futhi. Kulokhu, kufanele kuzwakale umsindo wokuhayiza womoya ophuma kuwo. Esikhundleni somlomo, i-compressor ene-gauge yokucindezela ingasetshenziswa futhi. Nokho, kufanele kuqikelelwe ukuthi ingcindezi ayikhuli kakhulu.

Ikhava i-Gasket Check

Kanye nama-valve, kufanelekile ukuhlola ukuqina kwe-gasket engenhla yesivalo se-radiator. Ngisho noma umoya ukhala lapho kuvulwa isivalo, lokhu kukhombisa kuphela ukuthi i-valve iyasebenza. Kodwa-ke, nge-gasket evuzayo, i-antifreeze ingahwamuka kancane kancane, ngenxa yokuthi izinga layo ohlelweni lehla. Ngesikhathi esifanayo, inqubo ehlanekezelwe iphinde ibonakale, lapho, esikhundleni sokuthatha i-antifreeze ethangini lokwandisa, umoya ovela emkhathini ungena ohlelweni. Lena indlela isikhiya somoya esakheka ngayo (“ukusakaza” uhlelo).

Ungahlola ipulaki ngokuhambisana nokuhlola i-valve yokuhlola. Esimeni sayo sokuqala, kufanele ifakwe endaweni yayo kurediyetha. Ukuze uhlole, udinga "ukufuthela" i-radiator ngeshubhu evela ethangini lokunweba (noma kunjalo, ukucindezela kufanele kube kuncane, cishe ibha ye-1,1), futhi uvale ithubhu. Ungalalela nje ukuhayiza komoya ophumayo. Kodwa-ke, kungcono ukukhiqiza isisombululo sensipho (igwebu), bese umboza ukhokho uzungeze umjikelezo (endaweni ye-gasket) nayo. Uma umoya uphuma ngaphansi kwawo, kusho ukuthi i-gasket iyavuza futhi idinga ukushintshwa.

I-Radiator cap tester

Abanikazi abaningi bezimoto ababhekene ne-depressurization yesistimu yokupholisa banesithakazelo embuzweni wendlela yokuhlola ukusebenza kwe-cap ye-radiator usebenzisa abahloli abakhethekile. Idivayisi enjalo yefekthri ibiza ama-ruble angaphezu kwezinkulungwane ezingu-15 (kusukela ekuqaleni kuka-2019), ngakho-ke izotholakala kuphela ngezinsizakalo zemoto nabakhandi bezimoto ngokuqhubekayo. Abanikazi bezimoto abavamile bangakhiqiza idivayisi efanayo kusukela ezingxenyeni ezilandelayo:

• Irediyetha embi kusukela kunoma iyiphi imoto endala. Isimo sayo esijwayelekile asibalulekile, into esemqoka ukuthi ukuze ibe nethangi elingaphezulu. Ikakhulukazi ingxenye lapho ukhokho unamathiselwe khona.
• I-sandpaper kanye "ne-welding ebandayo".
• Ingono evela egumbini lomshini.
• I-Compressor enegeji yokucindezela enembile.

Ukushiya imininingwane yokwenziwa kwedivayisi, singasho ukuthi i-tank ye-radiator enqanyuliwe, lapho wonke amaseli acwiliswa khona ukuze umoya ungaphumi kuwo, kanye nezindonga eziseceleni ezinenhloso efanayo. Ingono yegumbi lomshini, lapho i-compressor ixhunywe khona, ixhunywe nge-hermetically kolunye lwezindonga eziseceleni. khona-ke ikhava yokuhlola ifakwe esihlalweni sayo, futhi ingcindezi isetshenziswa ngosizo lwe-compressor. Ngokusho kokufundwa kwegeji yokucindezela, umuntu angahlulela ukuqina kwayo, kanye nokusebenza kwama-valve akhelwe kuwo. Inzuzo yale divayisi yizindleko zayo eziphansi. Okubi - inkimbinkimbi yokukhiqiza nokungeyona yonke indawo. Okusho ukuthi, uma isembozo sihluka ngobubanzi noma intambo, khona-ke idivayisi efanayo kufanele yenzelwe yona, kodwa isuka kwenye i-radiator engasetshenziswa.

Ngesihloli sekhephu yerediyetha, ungabheka ububanzi bengcindezi yokusebenza kwabo. Kuzohluka ezinjini ezahlukene. okungukuthi:

• Injini kaphethiloli. Inani lokucindezela lokuvula levalvu eyinhloko ngu-83…110 kPa. Inani lengcindezi yokuvula yevalve yevacuum ngu -7 kPa.
• Injini ye-diesel. Inani lokucindezela lokuvula levalvu eyinhloko ngu-107,9±14,7 kPa. Ingcindezi yokuvala yevalvu yevacuum ingu-83,4 kPa.

Amanani anikeziwe angama-avareji, kodwa kungenzeka ukuthi aqondiswe yiwo. Ungathola ulwazi oluqondile mayelana nezingcindezi zokusebenza zamavalvu amakhulu kanye ne-vacuum kubhukwana noma ezinsizeni ezikhethekile ku-inthanethi. Uma kwenzeka ukuthi i-cap ehloliwe ibonisa inani lokucindezela elihluke kakhulu kulokho okunikeziwe, kusho ukuthi linephutha futhi, ngakho-ke, lidinga ukulungiswa noma ukushintshwa.

Ukulungiswa kwekepisi ye-radiator

Ukulungisa isivalo serediyetha ngokuvamile akunakwenzeka. Ngokunembayo, umphumela cishe uzoba mubi. Ngakho-ke, ungazama ngokuzimela ukufaka esikhundleni se-gaskets yenjoloba esivalweni, uhlanze ukugqwala emzimbeni wayo, futhi uyipende kabusha. Kodwa-ke, uma intwasahlobo ekwakhiweni ibuthakathaka noma enye yama-valve (noma amabili ngasikhathi sinye) ihluleka, khona-ke ukulungiswa kwawo akunakwenzeka, ngoba umzimba ngokwawo ezimweni eziningi awunakuhlukaniswa. Ngakho-ke, isixazululo esingcono kakhulu kuleli cala kungaba ukuthenga i-cap entsha ye-radiator.

Iyiphi ikepisi yerediyetha okufanele uyigqoke

Abashayeli bezimoto abaningi asebeqale ukuhlola nokufaka esikhundleni sekhava eshiwo banentshisekelo yombuzo wokuthi yiziphi izembozo ezingcono kakhulu ze-radiator? Ngaphambi kokuphendula lo mbuzo, udinga ukunaka ngokushesha iqiniso lokuthi ikhava entsha kufanele ibe nezici zokusebenza ezifanayo nalezo ezishintshwayo. okungukuthi, babe ububanzi efanayo, intambo pitch, ubukhulu valve yangaphakathi, futhi okubaluleke kakhulu - kumele yakhelwe ingcindezi efanayo.

Imvamisa, ezimotweni eziningi zabagibeli zanamuhla, kudayiswa izembozo eziklanyelwe ukusebenza ebangeni lokucindezela lika-0,9 ... 1,1 Ibha. Kodwa-ke, ngaphambi kokuthenga, udinga ukucacisa lolu lwazi, ngoba ngezinye izikhathi kukhona okuhlukile. Ngakho-ke, kuyadingeka ukukhetha ikhava entsha enezici ezifanayo.

Sicela uqaphele ukuthi ungase futhi uthole okuthiwa amakepisi werediyetha ashuniwe athengiswayo, aklanyelwe ukusebenza ngaphansi kwezingcindezi eziphakeme, okungukuthi amabha afika ku-1,3. Lokhu kwenziwa ukuze kwandiswe indawo yokubilisa ye-antifreeze kakhudlwana futhi ngaleyo ndlela kwandise ukusebenza kahle kwenjini yomlilo yangaphakathi yemoto. Izembozo ezinjalo zingasetshenziswa ezimotweni zezemidlalo, izinjini eziklanyelwe ukusebenza ngamandla amakhulu, kodwa isikhathi esifushane.

Ezimotweni ezijwayelekile ezisetshenziswa emjikelezweni wasemadolobheni, izembozo ezinjalo azifaneleki ngokwengxenye. Uma zifakiwe, kuvela izinto eziningi ezingezinhle. Phakathi kwazo:

• Umsebenzi wezakhi zesistimu yokupholisa "yokugqoka". Lokhu kuholela ekwehleni kwesamba sensiza yabo kanye nengozi yokwehluleka ngaphambi kwesikhathi. Futhi uma ipayipi noma i-clamp iqhuma ngenxa yokucindezela ngokweqile, lokhu kuyingxenye yenkinga, kodwa lesi simo singaphela sibi kakhulu, isibonelo, uma i-radiator noma ithangi lokunweba liqhuma. Lokhu kakade kusongela ukulungiswa okumba eqolo.
• Insiza ye-antifreeze eyehlisiwe. Noma iyiphi into epholile inebanga elithile lokushisa lokusebenza. Ukudlula kuyo kunciphisa ukusebenza kwe-antifreeze futhi kunciphisa kakhulu isikhathi sokusetshenziswa kwayo. Ngakho-ke, uma usebenzisa izembozo ezishuniwe, kuzodingeka ushintshe i-antifreeze kaningi.

ngakho-ke, kungcono ukuthi ungalingi, futhi ulandele izincomo zomkhiqizi wemoto yakho. Ngokuqondene nezinhlobo ezithile ze-radiator caps, ziningi kakhulu, futhi zihlukile ezimotweni ezahlukene (zezimoto zaseYurophu, zaseMelika, zase-Asia). Kungcono ukuthenga izingxenye ezisele zangempela. Izinombolo zabo ze-athikili zingatholakala emibhalweni noma ezinsizeni ezikhethekile ku-inthanethi.

isiphetho

Khumbula ukuthi isivalo serediyetha esisebenzisekayo siyisihluthulelo sokusebenza okuvamile kwenjini evuthayo yangaphakathi yanoma iyiphi imoto enesistimu yokupholisa evaliwe. Ngakho-ke, kufanelekile ukuhlola isimo sayo hhayi kuphela lapho ihluleka (noma izinkinga zaqala ekusebenzeni kwesistimu yokupholisa), kodwa futhi ngezikhathi ezithile. Lokhu kuyiqiniso ikakhulukazi emishinini emidala, kanye/noma imishini esebenzisa amanzi noma i-antifreeze ehlanjululwe ohlelweni lokupholisa. Lezi zinhlanganisela ekugcineni zilimaza impahla yekhava, futhi iyehluleka. Futhi ukuwohloka kwezingxenye zayo ngazinye kusongela ukunciphisa indawo yokubilisa yesipholile futhi kushise kakhulu injini evuthayo yangaphakathi.

kuyadingeka ukukhetha isembozo esisha ngokuya ngemingcele eyaziwa ngaphambilini. Lokhu kusebenza kokubili kubukhulu bayo bejometri (ububanzi besivalo, ububanzi be-gasket, amandla asentwasahlobo) kanye nokucindezela okwenzelwe yona. Lolu lwazi lungatholakala kubhukwana noma umane uthenge isivalo serediyetha esifana nalesi esifakwe ngaphambili.
